ADJUSTMENT OF THE NUMBER OF CENTRAL PROCESSING UNITS TO MEET PERFORMANCE REQUIREMENTS OF AN I/O RESOURCE

摘要

A plurality of central processing units (CPUs) are allocated as a set of dedicated CPUs for processing tasks of an input/output (I/O) resource. In response to determining that a CPU utilization for the set of dedicated CPUs is less than a first predetermined threshold, at least one CPU of the set of dedicated CPUs is configured as a reserved CPU to execute tasks for one or more entities other than the I/O resource. In response to determining that a CPU utilization for the set of dedicated CPUs is greater than a second predetermined threshold, the reserved CPU is configured as a dedicated CPU to process tasks for the I/O resource.
